            </form>
        </section>

Above is my code for my php project, but the frontend prints out both successfully deleted and added. How do I make it only to print successfully added if I press the "Add Category" button and only prints out successfully deleted if I press the "Delete Category" button? I have inserted the screenshot of the problem below.

There are so many things wrong that the comment is inadequate

1. Your forms doing a post, so you have to use the $_POST not $_GET
2. You are not setting $_GET['error']
3. You need to use the name attribute for the input/button

<input type="submit" value="Add Category" name="addcat">

<input type="submit" value="Delete Category" name="delcat">

4. Then check which button has been pressed and execute the appropriate code.

if isset($_POST['addcat']) or if isset($_POST['delcat'])

5. Depending on the code not posted, you may need separate error variables such as $erroradd and $errordel.
